30
air quality for USP 797
inside hood must be ISO 5 or better
buffer area (SEC where PEC is located) must be ISO 7 or better
anteroom (adjacent to SEC - hand washing/garbing) must be ISO 8 or better if open into positive-pressure buffer area or ISO 7 or better if opens into negative-pressure buffer area
31
HEPA filters
>99.97% efficient in removing particles as small as 0.3 microns
in vertical airflow BSC/C-PEC, HEPA at top
in laminar airflow workbench (LAWF) or PEC, HEPA at back - horizontal airflow
direct compounding area (DCA) should be done where air is coming directly out of HEPA filter (first air)
32
ISO air quality inside of PEC

previously MSDS
for those working with hazardous materials
39
hazard communication program
must have designated individual for creating SOPs on worker safety (includes wearing ASTM D6978-rated gloves with counting or packing)
includes written plan with details of HD safety
men and women with reproductive ability must confirm in writing they understand the risks of handling HDs
40
lower-risk HD activities
counting and packaging tablets
can do an Assessment of Risk for lower risk drugs to avoid following all USP 800 if not being manipulated - if no AoR, follow USP 800; review AoR every 12 months
41
USP 800 physical space basics
hoods/buffer rooms for HDs include containment (C-PEC)
42
C-PECs for HDs
BSCs have vertical laminar airflow and negative air pressure
for sterile HDs - must be BSC Class II (most common) or III
CVEs: for non-sterile only; powder containment, negative air pressure
CACIs: closed-front C-PECs that are often in C-SCA
43
non-sterile and sterile HD in same space
preferable to separate non-sterile and sterile
can make non-sterile HDs in C-PEC if: C-SEC has ISO 7 or better, separate sterile and non-sterile C-PECs >=1 m apart
44
negative air pressure
required in C-PECs, C-SECs, and C-SCAs
45
HD air changes
ACPH = air changes per hour
non-sterile HD must have >= 12 ACPH
sterile C-SEC must have >=30 ACPH
C-SCA must have >= 12 ACPH
46
HD external exhaust
required for air with HDs
cannot be recirculated
alternative: use redundant HEA filters (has multiple HEPA filters in a series)
47
HD storage
store separately from non-HD
negative-pressure room of >=12 ACPH
48
compounding staff training/testing
hand hygiene, garbing, gloving - pass gloved fingertip test
49
gloved fingertip test
required initially and annually (if low-medium risk CSPs) or semi-annually (if high-risk CSPs)
collect gloved sample from each hand with tryptic soy agar (TSA)
incubate for 2-3 days
look for colony-forming units (CFUs)
pass: initially need 3 consecutive gloved fingertip samples with zero CFUs for both hands
ongoing: at least 1 sample from each hand with goal <=3 CFUs for total
50
media-fill test
if compounder is preparing CSP in aseptic manner
perform initially and at least annual for low-medium risk
tryptic soy broth used instead of drug
turbidity means contamination
pass: after 14 days, stays clear
51
temperature monitoring
document
SEC (buffer room) check once daily and kept <=20 C/68 F
refrigerator and freezer checked daily
refrigerator: 2-8 C
freezer w CSPs no vaccines: -25 to -10 C
freezer w CSPs + vaccines: -50 to -15 C
52
air sampling
do at least every 6 months by certified person or qualified compounding staff member
53
surface sampling
periodically test: at least every 6 months for HD
tryptic soy agar with polysorbate 80 and lecithin added to neutralize disinfecting agent
perform at end of day
all regularly exposed surfaces (inside PECs, work surfaces) should be tested
results should indicate 0 CFUs
take action if >3 CFUs for ISO 5, >5 CFUs in ISO 7, and >100 CFUs in ISO 8 area
54
air pressure testing
confirms differential between two spaces
ensures airflow is unidirectional
check pressure gauge at least daily or preferably with every work shift
55
humidity testing
check at least daily
56
keeping sterile compounding area clean
preferably PECs and C-PECs running at all times
if power outage - stop compounding; clean PECs with germicidal agent and disinfect with sterile 70% ISA
if CPEC - sanitation needed if power turned out
run PEC/C-PEC for at least 30 minutes before compounding if power turned off
lint-free wipes used to clean PEC
clean with germicidal agent then disinfect with 70% IPA
use slight overlapping, unidirectional strokes
replace used wipes often
clean top to bottom, back to front (cleanest areas
cleaned first)
sterile work: clean counters and floors with germicidal and sterile 70% IPA every day
HD: sanitize work area at end of shift
monthly: clean ceiling, walls, shelving, chairs, bins, carts
57
HD cleaning
sanitize by deactivating, decontaminating, cleaning at least daily
sterile must be disinfected
use wetted wipes for sanitizing agent
wear appropriate PPE
deactivation and decontamination: use bleach or peroxide
neutralize bleach afterwards
58
black waste bin
Bulk HD waste: containers with visible amount of HD, supplies used to administer/clean spills of HD
59
yellow waste bin
trace HD waste
empty syringes, IV bags, used PPE
60
red waste bin
non-HD sharps
61
drug exposure
1) remove garb that has drug on it
2) cleanse affected skin with soap and water
3) eye exposure: flood with water or isotonic eyewash for >=15 min
4) obtain medical attention when warranted
62
HD exposure and spill management
eye and face protection if risk of HD spills/splashes
face shields with goggles preferable for HD
63
respiratory protection HD
when HDs unpacked and not contained inplastic: wear elastromeric half-mask with multi-gas cartridge and P100-filter until confirmed no breakage or spillage during transport
N95 respirator for most HD compounding
if risk of respiratory exposure: fit-tested respirator mask with gas canisters or powered air-purifying respiratory (PAPR)
64
HD spilled
SDS should be consulted on clean-up procedures
65
HD spill kit contents
gown
latex gloves
N95 respirator plus goggles
HD waste bag
chemo pads
HD spill report exposure form
66
HD procedure to cleaning up spill
put heavy duty gloves over ASTM D6978 (chemotherapy) - rated gloves
put in bulk HD waste (black bin)
67
administering HD
two pairs of chemotherapy gloves required
gown required if IV HDs
closed-system drug transfer devices (CSTDs) must be used by nurses for administration
chemo pins used to prevent HDs from aerosolizing
CSTDs used to transfer whenever possible to keep HDs in device - reduce leaks/spills from reconstituting dried powders into solutions
CSTDs recommended when compounding HD and required for administering antineoplastics
CSTDs have build-in valve that equalizes air pressure
manipulate (crushing tablets) in plastic bag
68
HD disposal
outer chemo gloves go to yellow waste bin inside C-PEC or put in sealable bag if outside C-PEC
chemo gown and outer shoe covers taken off before leaving negative-pressure area and go in yellow waste bin
put trace antineoplastic waste (empty vials, empty syringes, empty IV bags, IV tubes, used gloves, used gowns, used pads) go in yellow waste bin
bulk antineoplastic waste (unused/partially empty IV bags, syringes, and vials) - black waste bin
69
transporting HD
pneumatic tube cannot be used to transport liquid HD or any antineoplastics bc risk of breakage/contamination
70
garb for HD drugs
double ATM D6978 (chemotherapy) - rated gloves when compounding or cleaning up spills; single gloves for receiving/storage
non-sterile HD: if BSC or CACi not available: use double gloves, gown, mask, disposable pad for work surface
sterile HD: head covers, face mask, beard covers, two pairs shoe covers, liquid-impermeable gown, two pair chemo gloves
full-facepiece respirator or face shield with goggles
71
garbing for sterile compounding
remove coat, sweater, makeup, jewelry before going to ante-area; no artificial nails
done garb in ante-area dirtiest to cleanest
head/facial hair covers and face masks
then shoe covers where stepping over line of demarcation (second pair of shoe covers for HDs)
wash hands with soap and water, clean under fingernails, wash fingertips to elbows in circulation motion for 30 seconds
non-shedding gown (disposable required for HD and preferred for non-HD)
enter buffer area (SEC)
use alcohol-based surgical hand scrub (chlorhexidine or povidone-iodine if allergic)
put on sterile, powder-free gloves (2 pairs ASTM D6978 chemo gloves required for HD compounding)
sanitize gloves with 70% IPA routinely during compounding or if touch non-sterile surface
use all this garb with isolator/glove box unless manufacturer documents not required
if not visibly soiled, gown can be kept on clean side of anteroom and re-worn for later in shift
